Abstract
A fault indicator apparatus employs a single indicating device such as a light emitting diode (LED) to provide an indication of all zones within a plurality of zones which exhibit a predetermined condition being monitored. In particular, the invention is employed in a multi-zone intrusion system where a single indicator provides an output indicative of all zones which are not secure. The apparatus causes the indicator to blink the zone numbers in a continuous sequence and for example, if zones 2 and 5 were not secure the indicator would provide two flashes indicative of zone 2 and then provide a predetermined pause while then providing 5 flashes indicative of zone 5. The user by counting the flashes can then immediately determine which zones in the plurality of zones have been violated.
